Gas quality (GQ) tab / Sampled GQ

There are properties that are unique to the sampled Gas Quality (GQ).

• Sampling Organization. The organization that is taking the sample.

• Analyzing Organization.The organization that is analyzing the sample.

• Receiving Organization. The organization that is receiving the sample.

In addition, it is possible to configure how the sample time information is displayed in AVEVA Measurement Advisor.

Note: The desired Sampled Time Adjustment must be defined before the data is received. The adjustment will not be applied after the system has received the data.

There are four options:

• None. No time adjustment.

• Current Gas Day. Uses the field contract datetime of the current gas day.

• Next Gas Day. Uses the field contract datetime of the next gas day.

• Nearest Gas Day.Uses the field contract datetime of the nearest gas day.

  Note: The Nearest Gas Day is calculated by calculating the mid-point of the defined gas day. If the time of the data is less than the mid-point of the gas day, it is set to the current gas day. If it occurs on or after the mid-point of the gas day, it is set to the next gas day.

For example, if the sample was taken at 10/9/2015 11:00 A.M. and the contract hour was defined as 09:00 A.M., the gas day would begin at 10/9/2015 09:00 A.M. and end at 10/10/2015 at 08:59:59 A.M.

Applying the Sample Time Adjustment will result in the following:

• Current Gas Day adjusts to 10/9/2015 at 09:00 A.M.

• Next Gas Day would adjust to 10/10/2015 at 09:00 A.M.

• Nearest Gas Day adjusts to 10/9/2015 at 09 A.M.
